Product Description
Keller ball joints
are designed to fix the standard OEM ball joint design. Instead of using a
snap ring to hold the ball joint in, we use a threaded chromoly housing that
can’t get pushed through no matter what. Todd Keller’s original design is
still the high bar for ball joints that can’t pull out. And if you’re riding
with a lift and big tires, Keller Ball Joints for the Polaris RZR Trail S 900
will last longer than just about any other ball joint out there.
The Most Durable Ball Joint Around
Keller Ball Joints
aren’t just the first threaded ball joints on the market—they’re also the most
durable. Once you press the joint into your arm and thread the housing on the
back, there’s nothing that’s gonna get it out. Plus, the housings are made
with durable tool steel and the stud is made from a high-quality chromoly
alloy so they can take the heat. And since they’re easily adjustable and
greaseable, you can keep them running smooth for years.
You
Need Keller Ball Joints
Put Keller Ball Joints on your RZR Trail
S 900, quit relying on a flimsy snap ring, and forget about breaking your ball
joints. When you go on hard ride after harder ride without having to replace a
ball joint, the only thing you’ll regret is not upgrading sooner.
